Ultra-Miniature Pressure Compensated Flow Control Valve PCFCD-1


Beswick Engineering announces the release of an ultra-miniature Pressure Compensated Flow Control Valve with low friction diaphragm – PCFCD-1N1. The PCFCD-1N1 is designed to maintain a constant flow rate, which the customer can adjust, regardless of upstream or downstream pressure variations. It works with both liquids (incompressible fluids) and gasses (compressible fluids) but is primarily intended for the control of liquids. The pressure regulation is accomplished with a low friction diaphragm mechanism. Beswick has applied for patent protection on this unique valve.

The PCFCD-1N1 sets an industry standard for miniaturization. It is lightweight….tipping the scales at only 48 grams. Customers will find it particularly useful when space, weight, and precise liquid flow control are critical.

The PCFCD-1N1 controls flow rates of 0 to 4.2 gallons per hour of Water (0 to 20 cubic feet/hour of Air). It is especially suited for the control of low flow rates. The maximum rated inlet supply pressure is 500 psig. Both the inlet and outlet ports are tapped 10-32. The valve body is both small and lightweight allowing for convenient in-line mounting without the need for a panel mount thread. The PCFCD-1N1 is currently available in brass. Buna-N is the standard seal material. Fluorocarbon (Vitonâ) is optional.

Research Oceanographer Grant Deane of Scripps Institution of Oceanography at UC San Diego specified the PCFCD-1N1 in a “bubble smasher,” which he and Cary Humphries of Scripps designed to study bubble fragmentation.
